Undefined references when compiling C++ program
Hello,
when I try to compile this...
//zozo.cc
#include iostream
int main()
{
std::cout Salut std::endl;
return 0;
}
...with...
gcc zozo.cc
...gcc give me...
/cygdrive/c/DOCUME~1/travonz/LOCALS~1/Temp/ccuTTqP6.o(.text+0x2f):zozo.cc:
undefined reference to `std::cout'
/cygdrive/c/DOCUME~1/travonz/LOCALS~1/Temp/ccuTTqP6.o(.text+0x34):zozo.cc:
undefined reference to `std::basic_ostreamchar, std::char_traitschar
std::operator std::char_traitschar (std::basic_ostreamchar,
std::char_traitschar , char const*)'

std::endlchar, std::char_traitschar (std::basic_ostreamchar,

undefined reference to `std::ios_base::Init::Init[in-charge]()'
/cygdrive/c/DOCUME~1/travonz/LOCALS~1/Temp/ccuTTqP6.o(.text+0x88):zozo.cc:
undefined reference to `std::ios_base::Init::~Init [in-charge]()'
collect2: ld returned 1 exit status
if I compile: int main(){return 0;} it's ok !
Do I have to specifie linking libraries with the -l option ?
thanks for your help.

Use g++ zozo.cc instead.

Ugh!
Did you think of checking the email archives? Do you realize this question
is really not Cygwin-specific so it's off-topic? Anyway, use 'g++' to
compile C++ source.
